Complex interactions

The environment is complex. I love studying complexity, and observing ecosystems fascinates me because they are made up of many moving parts that each interact with the others in ways that are simple but in an overall way that is too complicated to predict reliably.

Several years ago, wolves were reintroduced to Yellowstone National Park. The expectation was that this would help manage the populations of deer and other large game. It did. But it also impacted the environment in a slew of unexpected ways in what's called a trophic cascade. This video explains it well:


Listening to whales, now available for all

When I was in sonar on submarines for the US Navy, I always enjoyed the hours spent listening to humpback whales off the coast of Hawaii. It interfered with our job, but it was also one of the highlights of the work for me.

Now the Jupiter Research Foundation has made at least some of their hydrophones available so that anyone can listen to whalesong live.


The wide, amazing range of human sexuality

Human sexuality is one of the most interesting topics in the universe to me... I've been studying it mostly informally (but some formal education) for most of my adult life. There is an amazing universe of orientations, desires, behaviors, and choices, and it's all fascinating.

And it scares the crap out of a lot of people. The thought of sexuality being anything other than one man, one woman is frightening to significant portions of the population. Which is unfortunate, since it results in so much hate in the world that is, essentially, a waste of everyone's time and energy.
